2.15.1.2
Mounting Options
The ENC82 may be mounted directly on the pipe run, with or without the sample
probe enclosed. Optional support legs are available for added support when
mounted on the pipe run.
Optionally, a free-standing kit may be used to mount the enclosure next to the
meter run.
2.15.2 Optional Features
The following is a list of optional features:
•
Calibration blend
•
DC power switch (large enclosure only)
•
Dual bottle rack
2.16 Sample Conditioning Modules (Optional Equipment)
For some NGC installations, it may be necessary to install an optional sample
system conditioning module to compensate for non-ideal natural gas samples.
These optional modules are pre-engineered to provide various levels of protection
and bypass flows (see
). All of the sample conditioning modules
include a level of particulate protection and come in two flow sizes: 50 CC and 450
CC per minute (see
).
For installations where the gas is ideal and the sample probe is located less than
10’ from the NGC, no sample conditioning module is required.
